沥青路面高温温度场的经验预估模型

Empirical Prediction Model of High-Temperature Field of Asphalt Pavement

通过长期测试3种典型沥青路面结构的温度数据,引入气温、太阳辐射、风速及湿度参数,建立了夏季高温期沥青路面日最高温度与日平均温度的经验预估模型,并与SHRP、LTPP模型对比验证所建模型的适用性.结果表明:所建立的沥青路面高温温度场预估模型具有较好的预估效果,且与SHRP、LTPP模型相比,本模型在预估当地沥青路面日最高温度时具有更好的精度.

The temperature data of three kinds of typical asphalt pavement structure was carried out by longterm tests, and the high precision experience forecast models of high temperature field of asphalt pavement were established by introducing the air temperature, solar radiation, wind speed and humidity parameters, and through compared with SHRP, LTPP models, the applicability was validated. The results show that, the high precision experience forecast models of high temperature field of asphalt pavement has a good forecast effect, and compared with the SHRP and LTPP models, the model in the paper has better precision in forecasting the highest temperature of the asphalt.
